Theoretical and Ezperimental Study of Solar Assisted Heat Pump System for Grain Storage Drying
A solar assisted heat pump system for grain in-store drying, which includes solar air collector and heat pump, etc., is proposed Deep bed drying model of grain are established. A demonstration system has been installed in a grain depot of Kunming in south-west region of china and experimental study on the system has been conducted. The results show that the system has reached the expected performance. In the designed ventilation condition, the efficiency of solar air collector is more than 60％. The total heating capacity of the solar assisted heat pump system can reach 102.7kw and 119.2kw in cloudy and sunny days, with solar assisted fraction at 23％ and 28％ respectively.
